Hi toasternz the bezel shouldn't be too much of a problem removing, all I done was simply push a case back knife or a sharp thin knife between the bezel and one of the watch lugs and it pooped straight off, may be worth putting a piece of tape over the.ug your going to lever on to stop danages, but it should nt be hard work to remove.
Also the mod would be a lot easier with the bezel off the watch, hope this helps buddy
